Those documents focus heavily on transparency, minimal data access, and secure handling of user data.<\/p>\n<p>If your workflow depends on \u201cclever tricks\u201d to avoid review or to reuse someone else\u2019s client ID \/ consent screen \/ redirect domains, you\u2019re building on quicksand. This article focuses on the stable path.<\/p>\n<h2>What \u201cAntigravity\u201d changes (and why AI agent builders get flagged faster)<\/h2>\n<p>Antigravity is positioned as an \u201cagent-first\u201d platform (tools, tasks, autonomous actions), and Google is actively shipping official Antigravity docs and materials.<\/p>\n<p>Agentic systems are higher-risk because they:<\/p>\n<ul>\n<li>Request broad permissions \u201cjust in case\u201d<\/li>\n<li>Execute actions at machine speed<\/li>\n<li>Touch sensitive surfaces (mail, drive, identity, admin)<\/li>\n<li>Encourage \u201cconnect everything\u201d integrations<\/li>\n<\/ul>\n<p>So your compliance bar is higher by default. The safe posture is to treat OAuth like a regulated interface: scoped access, clear purpose, verifiable identity, and strong token security.<\/p>\n<h2>Understand the three most common \u201cban triggers\u201d for Google Auth + AI tools<\/h2>\n<h3>Trigger A \u2014 Using unofficial auth \u201cbridges\u201d or token-harvesting patterns<\/h3>\n<p>Any tool that intercepts OAuth, asks for copied auth codes, or asks users to paste tokens is a red flag. Many unofficial plugins openly warn that accounts may be suspended.<\/p>\n<p>Safe rule: users should authenticate directly with Google via standard OAuth\/OpenID Connect flows, and your app should receive tokens only through approved redirect URIs.<\/p>\n<h3>Trigger B \u2014 Sensitive\/restricted scope misuse (or skipping verification)<\/h3>\n<p>Google categorizes scopes and requires additional verification for sensitive\/restricted scopes.<\/p>\n<p>If you request restricted scopes (or even many sensitive scopes) without completing the required verification steps, you risk:<\/p>\n<ul>\n<li>consent screen limitations<\/li>\n<li>blocked access for many users<\/li>\n<li>enforcement actions for policy non-compliance<\/li>\n<\/ul>\n<p>Google\u2019s policy compliance guidance and verification requirements are explicit about domain verification, consent screen correctness, and scope justification.<\/p>\n<h3>Trigger C \u2014 Automation that looks like abuse<\/h3>\n<p>Even with correct OAuth, behavior can trigger enforcement: excessive API calls, unusual login patterns, mass operations, scraping-like access, or repeated failures\/retries.<\/p>\n<p>This shows up operationally as:<\/p>\n<ul>\n<li>sudden token revocations<\/li>\n<li>sign-in blocks<\/li>\n<li>\u201csuspicious app\u201d warnings<\/li>\n<li>account protections kicking in<\/li>\n<\/ul>\n<h2>The \u201cSafe Stack\u201d for Google Auth in AI workflows<\/h2>\n<p>If you want to build an AI tool that integrates with Google safely, aim for this stack:<\/p>\n<h3>Layer 1 \u2014 Pick the right identity model<\/h3>\n<p>Use OAuth (3-legged) only when you need user data.<\/p>\n<p>Otherwise prefer:<\/p>\n<ul>\n<li>Service accounts (for server-to-server access) when supported<\/li>\n<li>Workload identity \/ application default credentials for GCP workloads<\/li>\n<li>API keys only for public, non-user-data APIs (rare for real user workflows)<\/li>\n<\/ul>\n<p>Google\u2019s authentication overview is a good map of the options and when to use them.<\/p>\n<h3>Layer 2 \u2014 Follow Google OAuth policies and user-data policy as \u201chard requirements\u201d<\/h3>\n<p>Your application needs:<\/p>\n<ul>\n<li>clear disclosures<\/li>\n<li>a published privacy policy (and configured in OAuth client)<\/li>\n<li>limited data collection and limited use<\/li>\n<li>secure storage and handling of tokens and user data<\/li>\n<\/ul>\n<h3>Layer 3 \u2014 Least privilege scopes (by design, not as an afterthought)<\/h3>\n<p>Google explicitly recommends using non-sensitive scopes where possible, and minimizing overlap.<\/p>\n<h3>Layer 4 \u2014 Verification readiness (before you scale users)<\/h3>\n<p>If your app touches Gmail\/Drive\/Calendar in meaningful ways, assume you\u2019ll hit sensitive\/restricted scopes and need verification:<\/p>\n<ul>\n<li>sensitive scope verification<\/li>\n<li>restricted scope verification + possible security assessment<\/li>\n<li>verification help center guidance<\/li>\n<\/ul>\n<h2>A practical, production-grade checklist to avoid bans<\/h2>\n<h3>A) OAuth client hygiene (what Google expects)<\/h3>\n<ul>\n<li>Use your own OAuth client ID (never reuse someone else\u2019s).<\/li>\n<li>Verify every domain used by:\n<ul>\n<li>homepage<\/li>\n<li>privacy policy \/ ToS pages<\/li>\n<li>redirect URIs \/ JS origins<\/li>\n<\/ul>\n<\/li>\n<li>Ensure consent screen data is truthful and consistent with your app\u2019s behavior.<\/li>\n<li>Provide a real privacy policy URL in the OAuth configuration.<\/li>\n<\/ul>\n<p>Why it matters: domain mismatch and misleading consent screens are common reasons verification fails\u2014or apps get restricted.<\/p>\n<h3>B) Scope strategy that won\u2019t get you \u201cstuck\u201d in verification hell<\/h3>\n<p>Do this upfront:<\/p>\n<ul>\n<li>List every feature \u2192 map to the narrowest scope needed.<\/li>\n<li>Avoid \u201cfull access\u201d scopes unless absolutely required.<\/li>\n<li>If you can replace a restricted scope with a narrower alternative, do it.
